Automated UV Bonded Gaskets

Stockwell Elastomerics is committed to bringing the best performing materials to OEMs, giving them the competitive edge. Large gasket applications often use sub-par materials due to cost restrictions and wastes associated with traditional cutting. In 2013, Stockwell Elastomerics made a capital investment in a custom, automated ultraviolet (UV) bonding system. This automated process, combined with four in-house waterjets and CNC die cutting, allows for precision bonded gasket joints. UV jointed gaskets offer the benefits of single piece gaskets with additional cost savings.

At a Glance: Benefits of UV Bonded Gaskets

Bonded corners for sealing against IP64, IP65, IP66, NEMA 4X

Cost savings for large gaskets

UL 50E recognized gasket materials

UL 94 flame rated materials available

Excellent memory and compression set resistant

Closed cell materials for ingress protection

UV and ozone resistant gasket materials

Flexible and seal at very low temperatures (-70°F)

Best Gasket Material for Enclosures

Silicone, closed cell silicone foam and closed cell silicone sponge are considered the best enclosure gasket materials. Silicone has excellent long term memory known as compression set resistance – meaning it continually rebounds after being compressed. Stockwell Elastomerics’ silicone foam and silicone sponge materials are UL 50E gasket materials, good for NEMA enclosures. UL 94V-0 recognized gasket materials are also available where flame rating is needed (e.g. gasket for T8 LED fixtures).
